It'll be interesting to see what they experiment with. One
(dystopian) thing they could try out is facial recognition. While
Google has banned facial recognition from apps in the Glassware
store, it's still technically possible for developers to make and
distribute apps with the technology.

There's already an app for Glass called NameTag that claims
to do just that. Its site says that it can recognize people's
faces from the camera, search social media for their profiles,
and then present you with a card full of information about them.

Now imagine that, but with access to criminal and civil records
and synced up with the "Minority Report" crime surveillance system the
city launched in 2012. The NYPD could know the exact identity
and location of nearly everyone in the vicinity of a police
officer equipped with Glass, in addition to the raw footage that
can also be captured on video.

Futuristic? Yes. Creepy? Sorta, yeah. Effective? Probably — and
in ways that you might not expect. As Electronic Frontier
Foundation staff attorney Hanni Fakhoury told the Daily Dot in a post earlier today:
"If they do something they’re not supposed to do, we can see it."
